Seadoo - whay are they better in Saltwater?

[Maverickfh]

We have been running HO's for years, thought about getting a seasdoo for salt water as they have the closed cooling system, do all models have a closed system? are there better models for salt water jet ski fishing? are there any other reasons I should be looking at seasdoo?

2 strokes are NOT closed loop. The 4-tecs are closed loop. (pretty sure all of them, even the early models).

Closed loop systems are better for corrosion and salt concerns. That said, they should still be flushed after use. When flushing, it flushes the exhaust and impeller area as this is the only area the salt water touches. One exception, if you have an intercooler, salt water runs through them as well.

They are "better" per say, but yes you need to do alot of normal salt maintenence to keep them going. The exhaust is open loop cooled.

Welcome to the best Seadoo site on the planet! Let me know if I can help further.
